Abstract

L'invention porte sur un système de transmission de signaux de référence contenant des informations sur l'état d'un canal et permettant d'extraire lesdites informations et de les transmettre à un relais ou un macro-terminal. sur une sous-trame comprenant le signal de référence. Le relais et le macro-terminal reçoivent le signal de référence en utilisant les informations de la sous-trame, puis extraient l'information sur l'état du canal en utilisant le signal de référence, puis transmettent à la station de base l'information extraite sur l'état du canal.
